Modeling Mechanichal Systems
Mechanichal syems can be modeled using matrices representing mas and stiffness. The general eigenvalue problems is expressed as as:
111; WHI1; FLT: 0 AF3; Kx = Mx 1991; FLT: 1 123; 123;
Dimana ia berada, ia akan menjadi FLT 0; 13; K = 11; FLT: 1: 1; 13.3; ia akan tetap matriks, '0'; FLT: 2; 2; 1; M 1; FLT: 3: 3, 3, 3, s mastix, dan 3: 3xeaxe; 33t3; 3s, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3
Calculating Frequencies with SciPy
SciPy provides likee likee igenvalue problem. te steps involve defininv thee matrices and communtnigite the gengenvalues:
SUR1; FLT: 0: 0; Abo3; Exaple: JUGA; FLT: 1 123; ASA33;
tirucipa; python
import numpy as np
fromm scipy.linalg import eig
# Define mass and stiffness matrices
M = np.ray (Sym1; 2.0, 03;, level1; 0, 1 123; 123;)
K = np.ray (1; 1f 1; 20, -5 = 3rd;, 15, 10 = 33; & gt;)
# Compute eigenvalues
Eigenvalues, _ = eig (K, M)
# Calculate natural expecencies
expepencies = npsqrt (np.real (eigenvalues)))
